I am big fan of you and you IE workbooks and COD for routing and switching labs. Can you please help me with following query:

Why we cannot ping our own serial interface ip address until we put ip address on other serial interface to which we are connected to through back to back dce/dte cable. I know serial interfaces don’t have mac addresses, maybe some sort of layer 3 to layer 2 resolution issue which comes. Also when we ping our own serial interface ip address the response time is double as compare to ping the other connected serial interface ip address so that means request first go to other interface and then comes back, why does it happen so. My question might look stupid and I am really interested to know this stuff.

the id is on the first one of that increment making it 192.168.1.64/28

so the answer is supposed to be 192.168.1.64/28 which is what i punched in and it said it was wrong. i went back and tried it without the cidr notation just 192.168.164 and it said correct. this is incorrect the question asked for subnet id. subnet id’s on ccna’s test usually require the cidr notation to stay in the answer.
